The present invention relates to a' machine and method of producing novel and ornamental patterns or designs upon the fur surfaces of animalpelts or the like.

In the manufacture or preparation of shins or pelts tobe used as wearing apparel either as a trimming or as a garment, it is desirable to enhance the appearance of the fursurface by producing variations there in as by shearingthe nap or hair to produce, for example, a' series of waves.

A machine for accomplishing this result is setforth in mysPateut No. 1,737,085, granted November 26,1929.

In the said. application a practical and effective machine is disclosed in which the fur is moved over a conveyor into operative relation to shearing knives. A relative movement is produced between the conveyor and shearing mechanism and a sinuous or wavy surface is produced.

The present invention provides amachine in which a fur surface is ornamented without relative movement betweenthe same and the'shearingmechanism. e

In practicing the present invention a shearing machine of the usual type may be employed having the customary shearing mechanism and suction fan and a conveyor for delivering the furred surface ofthe skin to the shearing mechanism. To this machine I apply a guard element of such character as .to be capableof diverting portions of the fur from the knives. That is, the guard is so positioned that as the fur or hair is sucked toward the conveyor the guard permits certain portions of the hair to be sucked fully 'acrossthe knives while other portions of the hair are deflected from a straight path across the, knives andare made to take a lon er path and .are consequently sheared at different points.- For instance, a portion of the fur may be out adjacent theskins while portions adjacent to this shortportion may be of greater length. Theguard is, however, so arranged that a. gradual in crease in the length of the cut fur maybe produced at opposite sides of a short sheared portion. By moving the skin in .theusual manner on theeonveyor in com- 1927. Serial No. 184,281.

.bination with the guard, a trough or series of troughs may be produced in the surface of a skin. In addition to the production of a series of troughs I am able, by reasonof the novel guard, to produce the troughs of sinuous form. This is accomplished by imi parting a reciprocating movement to the guard in a direction transverse to the path of movement of the skin. Furthermore, it

is possible to give the guard such. move- I ment as to not only produce a series of sinuous waves but to impart upon each wave a super-imposed sinuous wave or instead of a wave, a series of zi "-zag troughs maybe produced, which in turn, may havetheir surfaces serrated or-sinuous. g

The various combinations and striking. effects possibleby reason of the present con struction will be more. readily understood drawing L) tion of aconveyor with respect thereto; I

Fig; 5 shows a cam 'for causing a horizontalmovement of the guard; v Fig. 6 indicates the .form of wave produced by the use of the cam shown in Fig. 5; Fig. 7 shows another form of cam; I Fig. 8 indicates the form of wave ;produced by the'cam shown'in Fig. 7 and 9,10, 11 and 12 showother modified forms of cams and the style of Wave or outv in thefur surface produced thereby As an example of one embodiment of the invention, a shearing machine is shown comprising a frame or supporting table. 10 having mounted thereon a rotary cutter 11 in operative relation to a bed-knife 12. The

rotary cutter may be mounted on a shaft 13 provided with @apulley (not shown) connected by abelt 15 to a motor 16 operable which they contact.

to actuate the cutter. A housing 17 may be mounted on the'lrame 10 to partially enclose the shearing mechanism, leaving an opening at the knives to permit the entrance of fur thereto when drawn thereacross by a suction produced by a fan or other means (not shown) in the usual manner. The housing 17 has an outlet 18 which may be connected to an exhaust apparatus as is well known to those versed in the fur shearing art.

For the purpose of applying a skin to the shearing mechanism, a conveyor 19, rotatable about a driving roller 21 and an idler roller 22 is suitably journalled in bearings at the sides of the machine. The driving roller '21 may be provided with a pulley 2% connected by a belt 24 to another driving pulley (not shown). The mechanism for driving the apron or conveyor of machines of this type is also well known and it is 'believed that the same will be fully understood. I I

' In carrying out the present invention, I "provide the above described machine with What may be termed a guard 25 which is in the form of a plate. his guard is disposed between the idler 22 of the conveyor and the shearing mechanism. The fur, therefore, as it is moved by the conveyor is disposed in such rel'ation't'o the guard as to brush or wipe the same and by providing a series of apertures 26 in the guard certain portions of the hair will be permitted to 0 "pass betweenthe knives while adjacent portions are shielded from the knives. By reason of the mere shielding of portions of the fur, the same may be sheared to form a series of troughs. The present invention, however, operates to control the shape of the troughs so that viewing the same transversely of theirleiigths the hair will have the form of a'true sine wave orthe form (if an inverse curve, This is accomplished by the novel shape of the apertures 26 which, as shown, are of triangular shape having the corners rounded, oi'ieof the corners being lowermost for the entrance of the fur as it is moved againstthe guard 25.

'As'in'or'e clearly shown in Figs. 3 and 4, the hair 27 is brushed against the edges of the 'aper'ture's'26. It will be seen that s'i'n'ce'the lower"corner 28 of the aperture is nearest to "the skin, the hair will be cut closerto the skin while the adjacent fur or hairs vvill be sheared at different points.

Since the'edges 29 and are inclined,,the

hair which is sucked thereover by: the fan will only be pulled across the knives to "the extent as permitted at the particular point on. the edge of the apertures ov'er Thus, when the fur is moved and the shearingmechanism is in operation minim-m undulating surface will be producod. It is t0 be understood that the particular form or configuration of the apertures may be varied as desired to vary the shape of the troughs produced or the depth of the troughs may be varied by a variation in the angular relation of the guard 25 to the shearing mechanism.

For the purpose of giving a more artistic appearance to the troughs, means are provided to make the same of sinuous form as shown diagrammatically in Fig. 6. This 1s the guard plate 25, the guard plate "being slidably attached to a plate 25 by means of headed pins 41 extending through slots 42 in the said guard. The lower or opposite end of the lever 37 may benormally held in contact with the cam 31 by a spring 43. A rotation of the cam 31 will operate. the

lever 37 to reciprocate the guard 25-and such action may be performed while a skin is being fed to theknives by the conveyor and what'may' be termed sinuous undulations will be produced iii the surface'of the fur such. as shown in Fig. 6.

The design may be further'elaborated by replacingthe cam 31 with a cam 44 as shown in Fl g. 7 in which case the undulations will not only be sinuous but will have a superimposed wave such'a's shown in "Fig. 8. If i a .z'igzag wave is desired, acam 45 such 'as shown in Fig. 9 may be employed and a waveasindic'ated in Fig. 10 will be formed. This form of wave may fhave an additional wave, as indicated in Fig. 12,'by employing 'a cam 46 as shown in Fig. 11. I

From the several examples given, I it will be evident that a great variety of combinations and distinctive designs'may be readily produced by a simple adjustment of the 1 machine "since both the depth and contour or the troughsmay be changed at will. The

yariation infdepth may be attained by provi'din'g the plate 25 'which supports' the guard 25', with an arcuate'extension 47% shown iiiFig. 4. 'Thisexte'nsion may have slot 48 to receive a bolt fastened'in the "side'oii the housing l7'so that'the guardmay 'be'secu'red in any desired inclined position.

From the foregoing, it will be evident that "a simple and efiective'machine is provided for ornamentii'ig lur surfaces and "although a preferred embodiment of the invention is shown and described herein, it is obvious that many modifications may be made iizo therein Nvithout departing from the spirit and scope of the invention as defined by the appended claims.
